The new school year is about to begin and we hope that the
cataloging activity helps you find the resources you need to
use technology in your mathematics classroom.

***FEATURED DISCUSSION
Computer Tools at PreK-2
Bethany asks, "I have some concern, and I've heard it voiced by
other teachers who teach at this level too, that using computer
tools to explore mathematics is really not appropriate."

***FEATURED DISCUSSION
Using TI-84 in Math A classroom
Suzanne writes, "Is it appropriate for math teachers to allow
use of the TI 84+ Silver in a Math A classroom? Are there any
Math A (high school course for students not ready yet to take
Algebra 1) teachers with an opinion to share?"

***FEATURED DISCUSSION
Special Needs
Brienne explains, "I'm new to math tools but have found many
links that will be an asset to Special Education and am curious
if there are any other Special Ed. teachers who have other
resources or recommendations for tools to use.

***FEATURED TOOL
Tool: Ball and Urn Experiment
Dept. of Mathematical Sciences, Univ. of Alabama at Huntsville
http://mathforum.org/mathtools/tool/14973/
Simulates drawing balls from an urn, with or without
replacement. Specify number of balls, number of red balls, and
number drawn.

***FEATURED TOOL
Tool: Five Frame
NCTM Illuminations
http://mathforum.org/mathtools/tool/12907/
In this interactive five-frames tool, users practice counting
and adding to ten. The frames help users think of numbers in
relation to 5.

***FEATURED TOOL
Tool: Fill and Pour
National Library of Virtual Manipulatives
http://mathforum.org/mathtools/tool/3046/
Fill a glass with the requested amount of liquid by filling,
emptying, and pouring between it and a second container. Click
the "New Problem" button to generate new parameters; "Challenge"
creates containers that make the target amounts impossible, and
invites you to "experiment and see if you can determine why the
given target cannot be obtained by working with the
given containers."
